摘要: High-concentration single-atom doping remains a formidable challenge due to the propensity for single atoms to form clusters or aggregate at elevated concentrations. Herein, high-concentration (10.8 wt%) Zn single-atom-doped porous tubular g-C3N4 (ZCN) was successfully obtained via a template-free, one-step calcination method, exhibiting excellent photocatalytic performance. The confinement of the pore walls suppresses the Zn atom's migration and aggregation, enhancing the Zn single-atom stability. ZCN exhibited excellent photodegradation performance against tetracycline with outstanding stability. Moreover, ZCN displayed remarkable sterilization performance, achieving a 100% inactivation of Staphylococcus aureus within 90 min of visible-light exposure. Density functional theory calculations demonstrated that the Zn single-atom sites act as pivotal photocatalytic active sites, with the presence of Zn single atoms notably augmenting charge separation efficiency. This work provides a novel approach for managing photocatalytic efficiency through enlarging single-atom doping, offering an avenue for pollutant photodegradation and sterilization.
